The descendants of Isaac and Ishmael have been entangled in a nearly 4,000-year dispute, which continues to manifest in modern conflicts. Ishmael, born to Abraham through Hagar, Sarah's surrogate, as described in Genesis 16, was the subject of a significant prophecy. The Angel of the LORD spoke to Hagar in the desert, declaring that Ishmael's descendants would be exceedingly numerous, unable to be counted for multitude. His name, meaning 'God has heard,' reflected the LORD's response to Hagar's affliction. The prophecy further stated that Ishmael would be a wild man, his hand against every man and every man's hand against him, dwelling in the presence of his brethren. This prophecy in Genesis 16:12 extends beyond Ishmael himself to the traits of his progeny. The description of him as a wild man, likened to a wild ass of the desert, suggests a proud, nomadic, independent, and uncontrollable nature, imagining himself unaccountable to others. The phrase 'his hand against every man' indicates a life of constant conflict and strife, similar to prophecies about Esau living by the sword. This aggressive, warlike manner provokes retaliation, ensuring that peace remains elusive as Ishmael's descendants draw others into conflict. The statement that he shall dwell in the presence of his brethren, primarily Isaac, implies a geographical proximity, generally to the east of Isaac's descendants, as Arabia lies east and slightly south of Israel. Historical tensions are evident in Genesis 21:8-9, where Ishmael, during a feast for Isaac's weaning, was seen scoffing or mocking Isaac, leading to conflict and the eventual expulsion of Hagar and Ishmael by Sarah. This incident typifies the ongoing discord between the children of Isaac and Ishmael. Further, Ishmael fathered twelve sons, forming twelve tribes, paralleling Jacob's twelve tribes, highlighting a mirrored structure in their lineage. In Psalm 83, a prophecy of a conspiracy against Israel includes the Ishmaelites among those seeking to cut off Israel as a nation, demonstrating the enduring hostility through to the end times.

In the cyclical nature of human activity, as Solomon describes, the story of Ishmael and Isaac illustrates recurring patterns of conflict driven by human nature. Ishmael, born through Abram and Sarai's human effort using Hagar as a surrogate, represented a birth according to the flesh. In contrast, Isaac, born to Sarah as divinely appointed, embodied a birth according to the Spirit. This distinction led to tension, as Sarah witnessed Ishmael, in his mid-teens, mocking the young Isaac after his weaning. God made it clear that Isaac, not Ishmael, would be the heir to the promises given to Abraham, establishing a covenant with Isaac and his descendants for an everlasting duration. This event set a precedent of divine choice, showing where God works and directs His purposes. As Paul later notes in Galatians, just as Ishmael persecuted Isaac, so too do those living according to the flesh often persecute the spiritual children of God, reflecting the predictable, repetitive nature of human enmity and self-preservation.

In the narrative of God's plan, the Angel of the Lord plays a pivotal role in the lives of Isaac and Ishmael, the sons of Abraham, appearing at critical junctures to guide events and fulfill prophecies. In Genesis 16, the Angel of the Lord first encounters Hagar, Sarai's Egyptian maid and Abraham's concubine, in the wilderness as she flees from Sarai's harsh treatment after conceiving Ishmael. The Angel commands her to return and submit to Sarai, promising that her descendants will be exceedingly numerous. He reveals that her son, to be named Ishmael, will be a wild man, in conflict with all, yet dwelling among his brethren. Hagar acknowledges this divine encounter by naming the Lord who spoke to her El Roi, the God who sees, and the well Beer Lahai Roi, between Kadesh and Bered. Fifteen years later, in Genesis 21, the conflict between Sarah and Hagar persists, culminating in Sarah's demand to cast out Hagar and Ishmael after Ishmael scoffs at Isaac during a feast for Isaac's weaning. God instructs Abraham to heed Sarah's voice, assuring him that Isaac will be the heir of the promise, yet promising to make a nation of Ishmael as Abraham's seed. As Hagar and Ishmael wander in the Wilderness of Beersheba, despairing when their water is depleted, the angel of God calls to Hagar from heaven, comforting her with the assurance that God has heard the lad's voice. He promises to make Ishmael a great nation, opens Hagar's eyes to a well of water, and ensures their survival. Ishmael grows in the wilderness, becomes an archer, and dwells in Paran, with his mother securing a wife for him from Egypt. In Genesis 22, the focus shifts to Isaac, the true son of promise, as the Angel of the Lord intervenes during Abraham's test of obedience on Mount Moriah. As Abraham prepares to sacrifice Isaac, the Angel calls from heaven, halting the act and affirming Abraham's fear of God for not withholding his only son. A ram is provided as a substitute sacrifice, and Abraham names the place The-Lord-Will-Provide, signifying God's provision. The Angel calls a second time, swearing by Himself to bless Abraham with descendants as numerous as the stars and sand, possessing the gates of their enemies, and through his seed, blessing all nations of the earth due to his obedience. These appearances of the Angel of the Lord to Hagar and Abraham regarding Ishmael and Isaac reveal His purpose in orchestrating events according to divine design. With Ishmael, He ensures his birth in Abraham's house and survival to fulfill prophecies of conflict and a united lineage. With Isaac, He confirms the covenant of promise, providing a substitutionary sacrifice and expansive blessings. In both narratives, the Angel of the Lord corrects human errors, commands specific actions, offers promises, and prophesies futures, demonstrating His authority and involvement in shaping the destinies of these two sons and their descendants.

The narrative of Isaac and Ishmael illustrates the profound promises of God to Abraham, highlighting themes of fruitfulness and spiritual distinction. Abraham had two sons, Ishmael, born to the slave woman Hagar in the ordinary course of nature, and Isaac, born to the free woman Sarah in accordance with God's promise. This distinction serves as an allegory for two different covenants, with Hagar representing bondage and Sarah symbolizing freedom. Spiritually, the divide between the descendants of Ishmael and Isaac is vast, as God's people are identified as children of promise, born of the Spirit like Isaac. While physically they share a lineage through Abraham as half-brothers, the spiritual separation underscores that God's chosen are to distance themselves from the ways of bondage, aligning instead with the freedom promised through Isaac.

The origins of antisemitism trace back to biblical times with the deep-seated discord between Abraham's sons, Ishmael and Isaac. This early conflict set a precedent for the animosity that persisted among their descendants, contributing to a long history of tension and hostility toward the Jewish people.

The enmity between Abraham's sons, Ishmael and Isaac, dates back over 3,500 years, rooted in the older son's jealousy and aggressive nature. This ancient hostility mirrors the current conflict between the Jews and the Palestinians, whose ancestry may trace back to Israel's longtime enemies, including the Ishmaelites. Such deep-seated antagonism, compounded by religious and economic disparities, makes explosive conflict between these groups sadly normal and unsurprising.

Most of the world's Christians and Muslims acknowledge the existence of Abraham. To the Christians, he was the father of Isaac, who begat Jacob, whose name was changed to Israel, making him the father of the twelve tribes of Israel. The Muslims recognize that Abraham was the father of Ishmael, who is considered the father of the Arabs. To this day, the descendants of Abraham through Isaac and Ishmael remain in perpetual conflict with each other, serving as further evidence of the accuracy of biblical history.

In Galatians 4:21-31, Paul employs an allegory to illustrate the distinction between two covenants through the lives of Abraham's sons, Isaac and Ishmael. Abraham had two sons: Ishmael, born of the bondmaid Hagar, and Isaac, born of the freewoman Sarah. Ishmael was conceived through carnal means, while Isaac's birth was the result of God's promise and a miracle, as Sarah was barren until God intervened. These two sons and their mothers symbolize the two covenants: Hagar and Ishmael represent the Old Covenant, which gives birth to bondage, and Sarah and Isaac represent the New Covenant, which gives birth to freedom. The Old Covenant, associated with Mount Sinai, produces bondage to sin and death because it offers no means of justification. In contrast, the New Covenant provides freedom through justification by faith in the sacrifice of Jesus Christ. Paul notes that, just as Ishmael, born after the flesh, persecuted Isaac, born after the Spirit, so it is now with those under bondage opposing those who are free. The scripture commands to cast out the bondwoman and her son, signifying that the Old Covenant and its bondage are to be set aside, as the son of the bondwoman shall not be heir with the son of the freewoman. Thus, believers are children of the freewoman, aligned with the New Covenant and the promise, as Isaac was.

Abraham, known as the father of the faithful and the friend of God, faced tests of patience in his spiritual journey. God promised Abraham a son, declaring that his descendants would be as numerous as the dust of the earth. For approximately ten years, Abraham and Sarah waited patiently, yet no child came. In their impatience, Sarah suggested that Abraham have a child with her maid Hagar. Abraham agreed, and this decision bore disastrous consequences that persist to this day. From this union, Ishmael was born, and as recorded in Genesis 16:12, he would be as a wild ass among men, his hand against every man and every man's hand against him, living to the east and on the borders of all his kinsmen, a perpetual enemy of Isaac's and Jacob's offspring. This rash act of impatience by Abraham and Sarah set in motion a legacy of conflict between the descendants of Ishmael and Isaac.

Ishmael and Isaac were half-brothers, sharing a common heritage as descendants of Abraham. Their familial connection underscores the broader kinship among all Semitic peoples, including the bitter feud between Islamic and Christian populations, which is essentially a conflict between cousins. Every individual on earth, as descendants of Father Adam and Mother Eve, is made in the image of God with the potential to become His children. Harboring hatred toward any ethnic group means hating our brothers and sisters, a stance contrary to the call for unity and peace. Often, the children of Ishmael have shamed professing Christians and Jews by highlighting their apostasy from God's covenant, serving as a reminder to reflect on shared reverence for God's laws, even if only in isolated concepts, to foster understanding and common ground.

In the biblical record of fatherhood, Abraham's relationship with his sons, Isaac and Ishmael, reveals stark contrasts in their upbringing and character. Ishmael, Abraham's first son, grew up to be a scoffer and mocker, as seen when Sarah observed him mocking at the feast for Isaac's weaning. Earlier prophecies described Ishmael as a wild man, hostile toward everyone, with every man's hand against him and his hand against every man. In contrast, Isaac, the promised son, displayed remarkable obedience and faithfulness to his father, evident during the near-sacrifice event where he submitted without struggle, trusting Abraham's assurance that God would provide. While the extent of Abraham's involvement in Ishmael's upbringing remains unclear, possibly influenced heavily by his mother Hagar the Egyptian, it is evident that Abraham invested significant personal time and energy in training Isaac. This dedication shaped Isaac to mirror Abraham closely, even repeating the same sin of lying to a king to protect his wife. God's relationship with Abraham enabled him to command and train his children in righteousness, ensuring the perpetuation of His ways to future generations, as affirmed when God declared His purpose for Abraham to guide his household in the way of the Lord.
